30 * PL-368 Device Management Plugin (DMP) Registers & Constants
32 * The "DMP" core used in Broadcom HND devices has been described
33 * by Broadcom engineers (and in published header files) as being
34 * ARM's PL-368 "Device Management Plugin" system IP, included with
35 * the CoreLink AMBA Designer tooling.
37 * Documentation for the PL-368 is not publicly available, however,
38 * and the only public reference by ARM to its existence appears to be
39 * in the proprietary "NIC-301 Interconnect Device Management (PL368)"
40 * errata publication, available to licensees as part of ARM's
41 * CoreLink Controllers and Peripherals Engineering Errata.
43 * As such, the exact interpretation of these register definitions is
44 * unconfirmed, and may be incorrect.
